Answer:
just by looking at the graph you can see that the y int is one, so that eliminates two answers already. Then the slope is rise over run. (best thing to remember in math. rise over run) so pick two points. (0, 1) and (4,0) were the first ones i saw. to get from those two points you go from (0,1) over 4 (thats your run) and from there down 1 (thats your rise) to get to (0,4). You would then do rise over run (and because your rise goes down its negative) to get -1/4 as your slope. The answer is slope= -1/4, Y intercept = 1
Answer:
6.5x10^7
Step-by-step explanation:
Answer: The interest is: " $ 64 .00 " .
_____________
Step-by-step explanation:
_____________
Take note of the formula:
" Ⅰ = Prt " ;
→ that is:
_____________
→ " Ⅰ = P * r * t " ;
_____________
In which:
_____________
" Ⅰ = the interest " ;
" P = the Principal amount of money " ;
" r = rate " (expressed as the "decimal form" of the percentage) ;
" t = time " (in years) ;
_____________
We are given:
_____________
P = $400 ;
r = 0.08 ;
{<u>Note of interest</u>: That is " 8% " ; since "8 % " = "(8/100)" ;
= "(8 ÷ 100)"
= " 0.08 ".}.
t = 2 ; {that would represent: " 2 (two) years".}.
_____________
We are to solve for "Ⅰ" ; the amount of "Ⅰnterest" :
→ To solve for "Ⅰ " ; we plug in our given values; and calculate:
_____________
→ Ⅰ = P * r * t ;
= 400 * 0.08 * 2 ;
= 64 .
_____________
→ Ⅰ = $ 64.00 .
